Abstract
Novel phosphonium salts of N-phosphonomethylglycine are disclosed herein, having the formula <IMAGE> in which R1, R2, R3, and R4 are independently selected from the group consisting of C1-C10 alkyl and phenyl. The compounds are useful as herbicides and plant growth regulants.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A compound having the formula ##STR3## in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 10 alkyl and phenyl.
2. A compound according to claim 1 in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 6 alkyl and phenyl.
3. A compound according to claim 1 in which R 1 , R 2 , R 3 , and R 4 are identical and are selected from the group consisting of C 1 -C 4 alkyl and phenyl.
4. A compound according to claim 1 in which R 1 , R 2 , R 3 , and R 4 are each methyl.
5. A compound according to claim 1 in which R 1 , R 2 , R 3 , and R 4 are each n-butyl.
6. A compound according to claim 1 in which R 1 , R 2 , R 3 , and R 4 are each phenyl.
7. An herbicidal composition comprising an herbicidally effective amount of a compound having the formula ##STR4## in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 10 alkyl and phenyl and an inert diluent carrier.
8. A composition according to claim 7 in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 6 alkyl and phenyl.
9. A composition according to claim 7 in which R 1 , R 2 , R 3 , and R 4 are identical and are selected from the group consisting of C 1 -C 4 alkyl and phenyl.
10. A composition according to claim 7 in which R 1 , R 2 , R 3 , and R 4 are each methyl.
11. A composition according to claim 7 in which R 1 , R 2 , R 3 , and R 4 are each n-butyl.
12. A composition according to claim 7 in which R 1 , R 2 , R 3 , and R 4 are each phenyl.
13. A method of controlling undesirable vegetation comprising applying to the vegetation in postemergent state an herbicidal composition comprising an herbicidally effective amount of a compound having the formula ##STR5## in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 10 alkyl and phenyl, and an inert diluent carrier.
14. A method according to claim 13 in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 6 alkyl and phenyl.
15. A method according to claim 13 in which R 1 , R 2 , R 3 , and R 4 are identical and are selected from the group consisting of C 1 -C 4 alkyl and phenyl.
16. A method according to claim 13 in which R 1 , R 2 , R 3 , and R 4 are each methyl.
17. A method according to claim 13 in which R 1 , R 2 , R 3 , and R 4 are each n-butyl.
18. A method according to claim 13 in which R 1 , R 2 , R 3 , and R 4 are each phenyl.
19. A method of regulating the natural growth or development of plants which comprises applying to said plants a regulating, nonlethal amount of a compound having the formula ##STR6## in which R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of C 1 -C 10 alkyl and phenyl, and an inert diluent carrier.
20. A method according to claim 19 in which R 1 , R 2 , R 3 , and R 4 are independently C 1 -C 10 alkyl.
21. A method according to claim 19 in which R 1 , R 2 , R 3 , and R 4 are identical and are each C 1 -C 4 alkyl.
22. A method according to claim 19 in which R 1 , R 2 , R 3 , and R 4 are each methyl.
23. A method according to claim 19 in which R 1 , R 2 , R 3 , and R 4 are each n-butyl.Join the waitlist — get patent alerts
